.BUNG non METALLIC BARRELS.

Be it known that'I, CHARLES F. PAPE, a citizen of the United States of America, residing atvandergrift, in the county of W'estmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Bungs for Metallic Barrels, of which the following is a "specification, reference being' had therein to the accom panying drawings.

The invention relates to metallic barrels and hasparticular reference to the novel construction of bung and bushing therefor as hereinafter set forth.

In the drawings: Figure 1 is a central section showing the bushing as attached to a metallic barrel and the bung in engagement therewith; Fig. 2 is a similar view showing 'the bung removed and a hose connected to the bushing for'filling the barrel; F ig. 3 is a similar view showing a tap secured to the bushing for withdrawing the contents from the barrel; and Figs. at and 5 are plan views respectively of the bushing and bung.

A is the wall of a metallic barrel; B is the bushing which may be formed of malleable casting, drop forging or other suitable material, and which is provided with a fiangeC for fitting against the inner face of the barrel wall and an outwardly projecting cylindrical portion D. The portion D is internally threaded to receive a corresponding threaded bungE, which is provided with a squared head F or other means for engaging a wrench or tool therewith.

It is usually necessary to provide a gasket for a metallic bung to insure sealing against leakage of the liquid contents of the barrel. The necessity for this bushing I avoid by providing the bushing B with an inwardlyextending flange G terminating in an outcone' or tapering portion H. The bung E is recessed and has its walls I tapered correspondingly to the taper of the cone H. Thus when thebung is screwed inward and is tightened against the cone H a liquid tight seal will be produced. For filling the barrel when the bung E is removed the threads of the portion D are adapted for engagement with a suitable coupling at the end of the filling hose. Inasmuch, however, as the diameter of the bung is greater than the diameter of the tap usually attached to the barrel, the flange G Specification of Letters Patent.

and cone H are internally threaded as indicated at J, so as to be adapted to receive the shank of the tap K.

The construction as described is one which may be cheaply manufactured, and the bush ingmay be readily attached to the barrel body, eitherby soldering, electric welding, or by any other of the usual and well-known methods of attachment. The tapering seat for the bung dispenses with the necessity of a gasket, and the different diameters of the threaded portions provide for attachment with either large or small connections.

What I claim as my invention is 1. A barrel bushing comprising an outwardly extending internally threaded portion and an internally threaded portion of lesser diameter, and a bung externally threaded to engage said outwardly-extending portion, and adapted to exteriorly engage said internally threaded portion.

. 2. A barrel bushing, comprising an outwardly extending internally threaded portion, an inner portion having an internally threaded aperture-of lesser diameter, an outwardly-extending conical seat surrounding said threaded aperture of.lesser diameter, and a bung threaded for engagement with said outwardly-extending portion and recessed to form a conical bearing complementary to the conical seat upon said bushing member.

3. Abarrel bushing, comprising a cylindrical member having an internally threaded portion at its outerend and a flange or head at its inner end having a concentric, internally threaded aperture oflesser diameter, a conical bearing formed upon said flange and projecting outward within the larger internally threaded portion, and a bung threaded forengagement with said larger internally threaded portion and having a recess with a conical wall for seating on said conical'bearing. 4. A barrel bushing, comprising a cylindrical member having a head at one end projecting beyond the periphery of the cyllarger internally threaded portion and bearing againstsaid portion of increased thickthreaded engageinent with one of said porness, the contacting faces being correspondtions and forming a lap joint with the other. 110
